Refer to the Figure P 8.4-3 in the text book.
It is clear from the Figure P 8.4-3P that the resistance value R is .
The first switch in the circuit is activated at and second switch is activated at.
For the simplicity of understanding and calculation, assume that is 0 s.
Thus, the first switch is activated at and the second switch is activated at .
The resistance R is to be neglected.
The steady state is at and in steady state capacitor acts as open circuit. In steady state condition, switch 1 is at position (a) and switch (2) is open.
